Brilliant EARTHSHIP Home Makes Off-Grid Life Look Easy

First things first; what is an Earthship? It’s defined as “a passive solar earth shelter made of both natural and upcycled materials.” Such a building, properly designed and executed, requires no utility services from the grid to operate.

The idea behind building an Earthship is that you don’t necessarily have to go back to basics to live off-grid – you only have to be conscious of how you live and your interaction/impact on nature. That is, you can embrace nature by building an environmentally sustainable and energy-efficient Earthship.

In a video published in the Tiny House Giant Journey YouTube channel, Jeff from Big Sky Earthship highlights the self-sufficiency of an Earthship — and we have to admit, he makes off-grid living look easy. Here’s a quick summary of how one of his Earthships in Montana works:

1. Shelter: The Earthship is largely made from recycled, reused, upcycled, and natural materials. Tires, old drums, and other types of scrap that are often thrown away in dumpsters are given a new lease of life.

2. Heating & Cooling: The house heats and cools itself passively and maintains a stable, comfortable temperature year-round, without the need for a centralized AC system.

3. Garbage Management: Aluminum cans and other garbage material are integrated into the structure of the building.

4. Clean Water: Household water is harvested from the roof, stored in cisterns, filtered, pressurized, and pumped into the house.

5. Water Recycling: Grey water from the sinks and shower is used to water the plants.

6. Food: As in any other off-grid living technique, growing your food is a big part of the Earthship owner’s journey of self-sufficiency.

The walk-through of Jeff’s Earthship is both inspiring and a pleasure to see the many ways people can co-exist sustainably with nature in off-grid living.

Here’s another feature about Earthships – sustainable homes for the future! This video by Earthship Biotecture, part one of a series, takes us on a guided tour of an Earthship, showing all of the systems that make it one of the most environmentally sound building ideas to date – this one has no utility bills to pay at all!

Earthships use a “passive solar design” (ie all of the windows are on the south side) to make the most of heat and light from the sun. Building thick walls from used tyres and earth gives them a large thermal mass that will absorb heat and make a dramatic difference “evening out” the temperature – helping the house to keep the house warm in winter and cool in summer. In some instances, this is so effective that no additional heating or cooling is required! Additional power is supplied by solar and wind generators.

The water recycling system is very efficient – rainwater is harvested and used water goes for irrigation or is treated within the home. So it’s possible to live completely off-grid with a set-up like this!

Another bonus: Earthships can provide a safe structure in areas where extreme weather is likely; they are made partly below ground, with very thick walls – so they can stand up well to hurricanes. They are currently being made in areas of the Philippines, following the recent typhoon disaster, and even on Easter Island!

40 million tyres are discarded yearly in the UK alone! An average Earthship home takes around 1,000 tyres to make – which means you have a free material to use in up to 40,000 houses a year! Where can you get that many tyres from? Scrap yards tend to charge even for old tyres, some of the bigger garages will not give them away as they have already contracted for them to be removed. One of the best ways is to go to smaller garages or independent suppliers – they are generally more willing to give them to you for free. It’s worth paying a small amount for a load so that you can obtain a receipt, which must declare that the tyres are “part worn” rather than waste (they are intended for re-use after all!) as you would need a special license to handle waste.

In the UK, tyres are banned from landfill and have to be disposed of separately because of the leaching of chemicals or gases (called “off-gassing”) from tyres as they degrade. This is mainly a problem when the tyres are shredded or exposed to the elements – whereas in a wall that is sealed on the inside and packed with earth, there is no risk to health. It’s possible to use other materials to give thermal mass to a wall if you’re concerned – the Earthship site has loads of info, including a full technical report on offgassing that you can see here:

Okay, here is the video:
